1. ### For you maths-people as I'm confused.

Does this notation mean: 0.999999... (going on infinately) ?
2. ### Ways to die

Well if that's all :rolleyes: We're talking about two different things here you seem to combine to one. As I see it there's killing and hurting which are two different things. Hurting someone can even be worse then killing someone.
3. ### I think there for I am or I am there for I think

We should first think about what we mean with existing. It is a word for something we experience. We experience existance of things. The main thing we experience is our own existance. So your own thinking proofs your existance for yourself... not your existing to others! We can only proof things...
4. ### Quiz question

This was a national science quiz question: What's the smallest amount of molecules for water to have the properties of a fluid. a)1 molecule b)2 molecules c)6 molecules What's the answer and why?
5. ### After Death

Being happy feels good and if it didn't there wouldn't be a reason for us to stay alive.
6. ### After Death

Everyones goal in life is to be happy. Why?, becuase we were made that way.
7. ### For you maths-people as I'm confused.

Thanks for clearing that up... though I still think it's weird.
8. ### For you maths-people as I'm confused.

How is it possible that I can write (for example) 1/3 and be 100% accurate while I couldn't write the same number in decimals being just as accurate? It has to do with our choice of system. But what is it exactly? I don't seem to grasp it or isn't there anything to grasp?
9. ### Have a cone and divide it into infinately small slices

This question just popped into my mind: Is there a difference between infinitely small and zero?
10. ### Have a cone and divide it into infinately small slices

erm... the difference would be infinitely small? But that would still be a difference which makes it possible to glue the slices together and get the cone back again rather then a cylinder. If the difference would be zero we would get the cilinder.
11. ### Have a cone and divide it into infinately small slices

If I have a cone and divide it into infinately small slices. Wouldn't both sides of one slice have the same area and wouldn't the next slice (and so on) have the same area as the slice before. So wouldn't your cone actually be a cylinder? My answer is no, because the reasoning is wrong. If I...
12. ### Physics AS exam

You say it yourself. It's a mathematical abstraction... in other words not to be confused with physical reality. Do note that I don't know anything about the fluid particle you're talking about.
13. ### Physics AS exam

Well if we stay at Newtons theory then the answer is clearly No. F = m * a --> a = F/m if m = 0 we will divide by zero which isn't aloud. There's no (classical) physical reality of an object with zero mass... it has no physical meaning. Something cannot have an infinite acceleration if it...
14. ### Need some help with Applications and Problem Solving .

The width of the mat is (if I read correctly) the width of the border that surrounds the picture. The problem now becomes: If I have a photo with area 96 and then put a border around the picture with the same area my total area (photo+border) will become 192. Now this equals...
15. ### Understanding of what inertia is?

Why is there even a need for the law of inertia? I thought of it and within classical Physics I don't see the need of the concept inertia at all. The natural state of an object is to stay at rest or move with a constant speed along a straight line. The law of inertia says mass provides...
